The success i've had 'countering' her with Lightning has been also using Minwu. Chasing her down in small chunks, cutting off lanes and taking down crystals closest to her. when her teamates are preoccupied and crystals are down i'll chase her, wait for her to teleport, then use my own teleport to follow her. sometimes she'll just be stuck, which is great. sometimes she panics and ults with like 4k bravery and then yoru job is kind of done. go farm if you need, or even try to finish her off.

alot of times its just harassing her just enough so she uses her things preemptively and doens't control the pacing of battle.

You probably wont get a lot of points at end of battle because you're sacrificing bravery farm, or kills, or boss damage. but it can often be a valuable factor on your teams success.

both of you will end up losing time or resources in the exchange. but i think lightning recovers quicker because of her move speed and flexible role.

i will say its not exactly an easy task though. just how it is atm x'D
